# WiFi Hotspots

## Wireless Overview

After accessing the router admin panel, go to ***"Network > Wireless"*** to the wireless overview page.

* **radio0 - Generic MAC80211 802.11bgn** is the 2.4GHz WiFi AP\
  SSID: Extender-WiFi-xxxxxx is the main hotspot\
  SSID: Guest-WiFi-xxxxxx is the Guest hotspot
* **SSID | Mode: Client** -- is the Wi-Fi relay connection. \
  It's not visible before setting up a Wi-Fi relay.
* **Associated Stations** are the active Wi-Fi networks and their working status.

You can turn off both client and master SSID by clicking the *"**Disable**"* button and re-activate it by clicking the *"**Enable**"* button.

## Edit WiFi Hotspots

On the above wireless overview page, click the ***"Edit"*** button on the row of related WiFi SSID to enter their configuration page.

**Cellular-WiFi-xxxxxx** is the main WiFi hotspot.\
**Guest-WiFi-xxxxxx** is the Guest WiFi hotspot isolated in a separate subnet.

*Note: "xxxxxx" indicates the MAC address of the WiFi AP module.*

### General

In the General Setup tab, you can monitor the network status and configure Wi-Fi operating mode, channel, bandwidth, and transmit power. Suggest using default settings unless there is a conflict.

* **Operating Mode** - Leave 802.11n standard (N mode) as default for maximum compatibility.
* **Channel** - Use the default Auto channel selection to let the router choose an unused channel. Or, if setting a manual channel, choose a lower channel <11 to ensure legacy device compatibility after setting the country code.
* **Operating Width** - Default 20MHz width instead of 40MHz helps avoid interference in dense WiFi environments.
* **Transmit Power** - Leave it in "Auto" mode to let the router adjust within regulatory limits. The max transmit power may be restricted below 21dBm depending on the country code for legal compliance.

### Country Code <a href="#country" id="country"></a>

In **Device Configuration**, click the **Advanced Settings** tab, check the Country Code field, and select the corresponding country code.&#x20;

It is essential to ensure the WiFi hotspot on your router meets the legal regulations in your country. The other configured WiFi networks will use the same device settings.

* **Country Code** - Select the appropriate country to ensure WiFi operates on legal frequencies and power levels.
* **Fragmentation Threshold** - Packet size before link layer fragmentation. Lower settings can help noisy links. 2346 bytes is generally recommended.
* **RTS/CTS Threshold** - Frame size threshold for RTS/CTS handshake. 2347 bytes is typically optimal.
* **Beacon Interval** - Configure the packet broadcast frequency. Lower times increase roaming support at the cost of throughput. Default 100ms is recommended.

### WiFi SSID

In the **Interface Configuration** section, click the **General Setup** tab. You can edit the WiFi hotspot name on the **ESSID** field.

Enable the checkbox of **Hide ESSID** to stop broadcasting the Wi-Fi hotspot but maintain the Wi-Fi connection. You should manually input the WiFI SSID and password to connect a new device when the ESSID is hidden.

* **Mode** - Leave as Access Point
* **ESSID** - Enter the WiFi hotspot name (SSID) for the WiFi hotspot. It is recommended not to include spaces or special characters.
* **Network** - Leave as the default LAN network
* **Hide ESSID** - Enable this option to disable SSID broadcast.
* **WMM Mode** - WiFi Multimedia is an automated way of handling Quality of Service (QoS). Turn it off for more compatibility with legacy WiFi devices.

### WiFi Password

Click the **Wireless Security** tab to customize the WiFi password in the **Interface Configuration** section.

* **Encryption** - Select the encryption method. Using "WPA2-PSK" or "Mixed WPA/WPA2" encryption with a strong password is highly recommended to prevent unauthorized access.
* **Cipher** - The recommended default is "Auto."
* **Key** - Enter and confirm a password (at least eight characters) that clients will use to connect. Do not leave this option empty after choosing the "Encryption" method above.

Click the ***"Save & Apply"*** button after customizing WiFi settings, and it will take 2\~3 minutes to reboot the WiFi hotspot. Then, use the new WiFi password to re-connect to the new WiFi hotspot name.
